The amount of a civil fine and/or response costs shall be deemed a debt owed to the City by the person(s) found in violation of Section 4-11.10 and therefore liable for a fine under Section 4-11.20 and fees under Section 4-11.25, and, if that person is a juvenile, then also his/her parents or guardians. Any person owing such fine and/or fees shall be liable in an action brought in the name of the City for recovery of such fine and/or fees. These recovery costs may include reasonable attorneys' fees incurred in the action if the City prevails, as the City reserves the right to seek to recover reasonable attorneys' fees, on a case-by-case basis, pursuant to California Government Code Section 25845, subdivision (c).

Nothing in this chapter shall be construed as a waiver by the City of Hayward of any right to seek reimbursement for actual response costs through other legal remedies or procedures.
The civil fines and fees imposed by this Article do not preclude other potential civil actions or criminal prosecution under any other provision of law, including but not limited to Penal Code Sections 272 and 415 and Business and Profession Code Sections 25658, 25658.2 and 25662.
